Sec. 60.63  Monitoring of operations.

    (a) The owner or operator of any portland cement plant subject to 
the provisions of this part shall record the daily production rates and 
kiln feed rates.
    (b) Except as provided in paragraph (c) of this section, each owner 
or operator of a kiln or clinker cooler that is subject to the 
provisions of this subpart shall install, calibrate, maintain, and 
operate in accordance with Sec. 60.13 a continuous opacity monitoring 
system to measure the opacity of emissions discharged into the 
atmosphere from any kiln or clinker cooler. Except as provided in 
paragraph (c) of this section, a continuous opacity monitoring system 
shall be installed on each stack of any multiple stack device 
controlling emissions from any kiln or clinker cooler. If there is a 
separate bypass installed, each owner or operator of a kiln or clinker 
cooler shall also install, calibrate, maintain, and operate a continuous 
opacity monitoring system on each bypass stack in addition to the main 
control device stack. Each owner or operator of an affected kiln or 
clinker cooler for which the performance test required under Sec. 60.8 
has been completed on or prior to December 14, 1988, shall install the 
continuous opacity monitoring system within 180 days after December 14, 
1988.
    (c) Each owner or operator of a kiln or clinker cooler subject to 
the provisions of this subpart using a positive-pressure fabric filter 
with multiple stacks, or a negative-pressure fabric filter with multiple 
stacks, or an electrostatic precipitator with multiple stacks may, in 
lieu of installing the continuous opacity monitoring system required by 
Sec. 60.63(b), monitor visible emissions at least once per day by using 
a certified visible emissions observer. If the control device exhausts 
gases through a monovent, visible emission observations in lieu of a 
continuous opacity monitoring system are required. These observations 
shall be taken in accordance with EPA Method

[[Page 310]]

9. Visible emissions shall be observed during conditions representative 
of normal operation. Observations shall be recorded for at least three 
6-minute periods each day. In the event that visible emissions are 
observed for a number of emission sites from the control device with 
multiple stacks, Method 9 observations shall be recorded for the 
emission site with the highest opacity. All records of visible emissions 
shall be maintained for a period of 2 years.
    (d) For the purpose of reports under Sec. 60.65, periods of excess 
emissions that shall be reported are defined as all 6-minute periods 
during which the average opacity exceeds that allowed by Sec. 
60.62(a)(2) or Sec. 60.62(b)(2).
    (e) The provisions of paragraphs (a), (b), and (c) of this section 
apply to kilns and clinker coolers for which construction, modification, 
or reconstruction commenced after August 17, 1971.
